The answer to this question depends on the specific foods being blanched. Boiling is the most common and widely used method, but steaming also works well for some vegetables.

When a food is scalded in hot water, it undergoes heat sterilisation. This process deactivates enzymes that are responsible for the deterioration of quality and texture in foods.
In addition, blanching reduces the number of microorganisms on food surfaces and assists subsequent preservation operations such as freezing or canning. However, excessively high temperatures and long processing times may cause damage to the tissues and protein denaturation as well as loss of color, flavor, and vitamins and minerals.

Aside from killing harmful bacteria, blanching also helps bring out the flavors and nutrients in certain fruits and vegetables. It can also make softer, more tender cuts of meat and fish.

This is an important thermal processing step that enhances preservation and quality by inactivating enzymes that are responsible for the deterioration in color, flavor and texture of foods. This is generally performed prior to freezing, drying or canning as a pre-heat treatment before the main heat-processing stage.
It can also soften tough vegetable tissue to facilitate filling into containers, and remove intercellular gases from the tissues that alter the wavelength of reflected light. This, in turn, brightens the color of some vegetables and increases their appetizing appeal on party trays with dip.

The most effective way to kill harmful bacteria is to immerse a food in boiling water for at least 30 seconds or more. This will deactivate the bacterial cell walls and release oxygen, which can then be removed using an airtight container or pressure cooker.
Besides the benefits of destroying bacteria, blanching can also clean the surface of a food and reduce bitterness. It can also brighten the color of some vegetables, such as broccoli and spinach.

If a food is over-blanched, it will lose its crunch and become mushy or soggy. This can be particularly true of vegetables that are too firm to boil for too long, such as carrots and broccoli.

While a lot of people don’t think about how often they cook their vegetables, it is actually quite common. Most people have boiled some type of veggie at some point, and it is an excellent way to help keep your veggies fresher longer. The best part is that blanching can be done with just a few simple tools – a large pot, a stove and a few minutes of time.
